Question

我尝试使用官方的Kibana和ElasticSearch图片，但他们只是退出并显示错误消息。在启动几秒钟后，容器的状态如下所示：

     Name             State               
------------------------------
elasticsearch        Exit 1                                                                             
elasticsearch1       Exit 78                                                                           
mongotest_kafka_1    Up        
mongotest_kibana_1   Exit 1

其中一张图片的错误讯息：

我不确定docker-compose.yml中的某些配置是否错误：

这需要在docker主机上配置（弹性堆栈有一些要求高于默认的Linux主机安装）。 Elastic has documentation on this process，包括虚拟内存设置。对于此特定错误，您可以运行以下命令：

equals

您希望在/etc/sysctl.conf中对此进行配置，以便设置在重新启动后仍然存在。

使用XPack设置ElasticSearch和Kibana图像
